PWM at UBS vs PWM and IB at Janney Montgomery Scott?

I'm a sophomore at a non-target school with no finance experience. I have good grades, clubs, etc, and have already done some decent networking. I was able to get two unpaid internship offers in Philadelphia for the summer. One is at UBS working in PWM under the head of the division, and the other is at Janney Montgomery Scott working half the summer in PWM and half the summer in IB. I'm having difficulty weighing the two.

I'm thinking that I want to get into IB after college and and will take appropriate steps next summer, but I'm wondering what some of you think about my choice between the two options. I know that transfer from PWM to IB is hard, but I feel like the bigger name might make up for that. Honestly, any advice helps and I'd love to get it.

Thanks
